SHEET-METAL FILING.

'No.esoas?.

To all whom 'it may concern:

Be it known that I, NORMAN E. MARsI-I, a citizen of the United States, residing at Des Moines, in the county of Polk and State of Iowa, have invented a new and useful Sheets Metal Filing, of which the following is a specification.

lIhe obj ect of my invention is to provide a sheet metal piling of simple, durable and inexpensive construction, so arranged that sheet metal plates of` considerable width may be employed, without danger of bending or buckling, to thereby minimize the work ofV driving, and. also so arranged that the piling may be easily withdrawn after use.

A further object is to provide'a piling of this kind which, when a number of piling members have been driven, will have at the joints thereof open chambers or wells, into which packing materialmay be easily inserted for the purpose of providing water tight oints.

My invention consists in the construction, arrangement and combination of the various parts of the device, whereby the obj ects contemplated are attained, as hereinafter more fully set forth, pointed out in my claims and illustrated in the accompanying drawings, in which Figure 1 shows a top or plan view of a number of sheet metal piling members united. Fig. 2 shows a similar view of a slightly modified form. Fig. 3 shows a side elevation of a number of sheet metal piling members embodying my invention, united with each other. Fig. t shows-a sectional viewon the linee- A of Fig. 3. Fig. 5 shows an enlargedl detail view of the connected edges of two sheet metal piling members of the form shown in Fig. 2, with packing devices inserted in the chambers or wells, and-Fig 6 shows a similar view of the form shown in Fig. 1, with a packing mate rial inserted in thechamber or well.

Referring to the accompanying drawings, the preferred form of the invention is shown in Figs. 1` and 6, and this comprises aser-ies of sheet metal piling members, each of which is formed of a fiat piece of sheet metal 10. Secured to one side of` said part at each edge, is an angle bar 11 connected with the part 10 by rivets 12.

Secured to the same side near each edge,

is a Z bar 13 having the part 111 extended at right angles to the part 10, and a part 15 extended at right angles to the part 1&1- in' a j l Specification of Letters Patent. Application inea March 1e, 1908. serial No. 420,949.

direction toward the adjacent angle bar 11. The parts of said bars that are at right angles to the sheet 10 are spaced apart. At the centerof each of the sheets 10 I have secured on one side an angle bar 16, and the other side a flat plate 17 held together by rivets 18; These latter serve to strengthen and reinforce the sheets 10 at the centers thereof, and the outer edge of the angle bar 16 is extended to position in line with the parts 15 of the Z bar so that if desirable, a wooden partition may be attached to these parts.. In practical use with this form of my invention, I first drive one of the piling members to position, and then place a second piling member of identical construction, in position with the partv 15 of the adjacent Z bar overlapping the edge of the part 10 ofthe first mentioned piling member, an the part 10 of the second piling member placed in engagement with the part 15 of the'Z bar on the adjacent edge of the first mentioned piling member.

rIhe angle bar 11l of each piling member is in engagement with the Z bars ofthe other member, and the chamber or well 19 is formed between them. The only place where any leakage would occur, would be between the adjacent ends of the angle bars 11, and obviously, if water was prevented from flowing through the chamber or well 19, from the `adjacent ends of theangle bars 11 at one side, to the adjacent ends of the angle bars 11 at the other side, then an absolutely water tight joint would be formed. By providing a chamber or well 19, packing material may be readily and easily inserted, that will prevent this leakage. In some instances I have found that leakage is eectively preventedby filling the chamber or well with clay or mud. If however, this is not effectual, a packing material such as cotton or hemp, orthe like, may be substituted, and packed tight in each chamber or well. In F ig.6 I have shown a packing material of cotton or hemp, indicated by the numeral 20. Another very efficient method of making the said joints water tight, is by providing soft boards such as shown in Fig. 5, and indicated by the numeral 21. rIhese parts have their ends beveled, and are of such size that they will fit diagonally in the chamber or well 19, and the opposite edges of the boards will engage the joints at the opposite corners of the angle bars, and if these boards are placed in position when i to .be connected `with the Y portions lby dry, the water inside of the chamber or well` 19 will cause them to swell sufficiently to form water tight joints. be easily withdrawn when desired, so that the piling members may be separately Withdrawn, and preserved for future use.

To provide for driving the piling members, I'preferably place on :top of each member to be driven, a protecting piece 22 with its sides overlapping the sides of the part. 10, and its central portion extended over the top of same, and -this part 22 is designed to receive the impact of the hammer, or weight used to drive the piling.

In the modified form shown in Fig. 2, I have formed a. structure which differs from :the form shown in F ig. 1, in that there are 4two chambers or wells provided at keach joint. ln this modification, the only change from the form shown in Fig. 1, is that the angle bars at the ends .of the joints 10 have the parts that are a-t right angles to the sheet, spaced apart yfrom the edges of the sheet. These angle bars are indicated by the numeral 23, and the two angle bars 23 of two adjacent sheets 10Vwill, when the sheets are connected, stand in position with their parts that are at rightvangles to the sheets 10 flat ,against each other, thus forming two chambers or -wells 24 on opposite sides of said angle bars. In this form of the invention, there is additional security against leakage, because the only way lthat water can pass through the piling would be at the joint on one side between the part 15 of the Z bar, andthe engaging portion of the sheet 10, into the first of the chambers or wells V24, and then it will have to pass kout of this chamber orwell into the next one before it could .escape between the part 15 of the other Z bar, and theV adjacent .portion of the other sheet 10, hence, it would have to pass through four packed sheets. In all other respects, the construction and operation of the form shown in Fig.;2 is similar `to that of the forni sho-wn in F ig. 1.

In Figs. 5 and 6, I have shown the Z bars piling sheet body means of bolts, instead of rivets, the advantage of this being that in case it is desired to wit-hdraw the piling, and they should be stuck together in such manner as to make their withdrawal impracticable, then the .bolts of the Z bars may be loosened to th-us permit one body portion to be readily and easily withdrawn from the other.

Having thus .described my invention, what I claim and desire to secure by Letters Patent., S- Y 1. YAn improvement in sheet metal piling, comprising two sheet metal piling members, each having at one edge, two laterally extended flanges spaced apart from each other,

the one having the flanges extended toward one side, and the other having the flanges These boards may extended toward the other side, the outer or `edge flange on `each member being inserted between the two flanges of the other member, said parts when assembled having a chamber or well between the two adjacent edge flanges.

2. An improvement in sheet metal piling, comprising two sheet metal piling members, each having at one edge two laterally extended flanges spaced apart from each other, the one having' the flanges extended toward one side, and .the other having the fianges extended toward the other side, the outer or edge flange on each member being inserted between the two fianges of the other member, said parts when assembled having a chamber or well between the two adjacent edge flanges, the flange of each member that is spaced apart from the edge being provided at its end that is farthest from the body portion with extensions projected toard the edge and arranged to overlap the edge of the opposite sheet metal piling body portion.

3. An improvement in sheet metal piling, comprising two sheet metal piling members, each having at one edge, two laterally extended iianges spaced apart from each other, the one having the iianges extended toward -one side, and the other having the flanges extended toward the other side, the outer or edge fiange on each member being inserted between the two flanges of the other member, said parts when assembled having a chamber or well between the two adjacent edge ianges, and a packing material placed in said well or chamber.

et. An improved sheet metal piling co1nprising two members, each having on one side near one edge, two portions spaced apart from each other, and extended substantially at right angles to the sheet, so arranged and disposed that when the two piling members are united, a chamber or well will be formed between the sheets and said portions, and a board inserted in said chamber or well and extended diagonally across it with its edges in engagement with the corners of the chamber or well.

A sheet metal piling member, comprising a fiat body portion, an angle bar secured to one side thereof near the edge, a Z-bar secured to the same side thereof and spaced apart from the angle bar and parallel with it, the outer portion of the Z-bar being ex- `tended in a direction toward the angle bar.

6. An improved sheet metal piling comprising two flat sheet metal body portions, each having near each edge at one side, an angle vbar with the part that extends outwardly from the body portion spaced apart from the edge of Athe body portion, and a Z bar secured to the body portion and spaced apart from said angle bar, the outer edge of the Z bar being extended toward the other, said flanges being so arranged that when the two sheet metal piling members 15 are connected, they will form an open chamber, or well, between the flanges, and said flanges being also so shaped as to prevent lateral movement of one piling member relative to the other.
